The reasons why farms use tumblers in the composting process are as follows.
1. To help oxygen enter is often called aeration. Compost fermentation
method is aerobic fermentation, which requires a lot of oxygen. However, after a period of natural fermentation, the oxygen in the pile will gradually decrease, making the fermentation slower. With the use of a compost turner, the oxygen in the compost pile can be fully ventilated during the turning process.
2. Reduce the temperature of traditional fertilizer, every once in a while with a shovel to turn the pile, you will find that there is white smoke, this white smoke is water vapor, water in the evaporation process will take away heat, so as to achieve the purpose of cooling. In the composting process, a reasonable temperature control is an important technical indicator. Too high a temperature will kill the nutrients in the organic raw materials. Using a pile turner can stir the compost inside and outside of the pile evenly, so that a large amount of water in the compost evaporates, thus effectively controlling the temperature in the compost.
3. Promote the fermentation process, so that the beneficial fermentation bacteria and fermentation materials fully and evenly contact, to promote the fermentation process.
4. Greatly improve the efficiency of work. Normal manual operation 2 days turnaround speed, the use of tank turning machine more than two hours to complete, uniformity is much better than artificial.
